Today, Ron Fortress is still a bridgehead for humanity to defend against the invasion of the Orkings. As long as the Ron Fortress does not fall, it will be difficult for the Ogins to cross the Ron Fortress and storm the hinterland of the Principality of Baya.

The so-called First and Second Austro-Pau Wars are even more of a joke in the legends of the Augins.

The so-called Diogin invaders in human history were nothing more than one or two unsurvivable Oagin tribes who carried out an almost hopeless attack on Ron Fortress. Because the tundra could not support so many Okin people, the dozens of huge tribes with thousands of people that originally existed on the tundra disappeared, and now scattered on the tundra are only small villages with dozens to hundreds of people.

Because there is no place on the wind and snow tundra that can provide a village of thousands of people to live on, the Aojin people who want to eat can only be scattered in the vast wind and snow tundra in the number of dozens and hundreds of people. Even so, food is still extremely scarce for the Okins, and every winter, some of the poorer Ogin people die of hunger and cold.

As a military fortress primarily used to defend against the Auguins on the tundra, it also controlled the Golden Road, an extremely important trade route between the Misty Forest to the west and the Otto Merchant Alliance and the Saint-Germain Empire to the east.

The origin of the name of the Golden Road is given by the merchants who traveled along this trade route, meaning that it can bring infinite wealth to anyone, and for those who have the ability but no opportunity, the opportunities brought by this road are as precious as if they were paved with gold!

The Golden Road starts with the Misty Forest, then follows the border between the Duchy of Baya and the Tundra to the east, and ends at San Francisco, the capital of San Francisco, at the junction of the four kingdoms of Baya, Otto, Saint-Germain and the Tundra, which is less than 50 kilometers away from the clear blue sea. After assembling in San Francisco, large quantities of goods were transported in batches to Pearl Harbor, 50 kilometers away, where countless merchant ships were waiting to transport them to any corner of the world.

The importance of this San Francisco was obvious to Invincible, but as far as he knew, San Francisco, a clear place of four wars, had not been the scene of major wars for a thousand years, but had become a zone of recklessness, and even the fifty-kilometer road that stretched along the border between the Otto Merchant Alliance and the Saint-Germain Empire to the sea became a default zone of freedom.

This strange situation has been going on for hundreds of years, and even the people of the current Otto Business Alliance and the Saint-Germain Empire know that their country has a golden road full of wealth and opportunity, and that a large number of people go to pan for gold every year. Only the Okin did not enter the area in large numbers because they had no concept of commerce, and only a few of the Okin came here with the team because of mercenary missions.

Invincible is not an Aokin, he comes from a modern society with a highly developed business, and he knows far more about the power and sources of money than the Aokin.

In fact, even the rare wise man Tu Meng of the Ao Jin people has never paid attention to the power of commerce, and the reason why Tu Meng mentioned the Golden Road is just because of the description of the prosperity of the Golden Road by human beings, hoping that the invincible can find a way to make a fortune, because Tu Meng is indeed not very sensitive to business, and he has never done any business, and his way to make money in the human kingdom is limited to completing mercenary tasks or adventurer missions.

As San Francisco, which is located at the junction of four countries, it is a trip that Invincible attaches great importance to.

Especially under the premise that Emily's themed business team has been finalized, the Golden Road must be put on his agenda. Compared to the Golden Road, Misty Town is just a remote raw material production area, and although it has a price advantage, it cannot continue to develop. But what makes Invincible a little excited is that the southeasternmost part of the snowstorm tundra will be adjacent to the sea, compared with the world's backward land transportation, the huge profits brought by sea transportation are what Invincible desires.

It is a pity that San Francisco has been able to stand at the junction of the four countries for so long, but no country has expressed interest in it, so it has to be a concern.

When he saw the walls of San Francisco, he was suddenly shocked, and a huge city that was incomparably towering like a cloud appeared in front of him.

As far as invincibility is concerned, the city is so huge, especially the towering walls that are unique to ancient times, different from the isolated towering of modern buildings, like a huge fortress, a huge coercion that can make ordinary people feel breathless because of this.

Invincible sighed for a long time before he sighed, this huge ancient building was probably only comparable to some of the ancient palace ruins of the Federation in his world, but unlike those ruins, this city was alive!

Under the dark night sky, a huge city that is so brilliant that it almost obscures the light of the stars and moon, which is so similar to those scenes of the invincible impression, but there are no more familiar people and familiar things here. There is only a whole new world waiting for him to understand and conquer......

San Francisco is also known as the city that never sleeps.

At the huge city gate, countless carriages are still busy shuttling, and the guards of the city gate are still continuing their work, checking ...... Release, re-inspection and re-release. The title of the city that never sleeps doesn't come out of nowhere, not only the gates that are open all night, but also the taverns and shops that are open all night, and the casinos and brothels, which were originally midnight venues, are many times more prosperous than other cities.

Invincible looked at the thirty-meter-high city wall with some distraction, and sighed in his heart: No wonder the Aujin people have never had the idea of fighting San Francisco, you must know that even the military town of Ron, which is known as the first level of Baya, its wall is only fifteen meters high, only half of the San Francisco. Even the Aojin people who could not be captured by Ron Fortress naturally would not consider attacking this terrifying city.

The city's defense system is extremely advanced and fast.

In the information that Tu Meng told the invincible, it included an elite mercenary team of more than 100 people stationed at each city gate, four magic cannons, fifty huge heavy machine crossbows, and two high-level magicians. In addition, the magic technology is used to create the Ten Thousand Jin Broken Dragon Gate, which can be retracted in one minute and closed in five seconds.
